9 Claims. (Cl. 108 -17) This invention relates to metal shingles to be used in roofing or the like; and the principal object thereof is to provide :a shingle designed to facilitate easy application to the roof or the like; also a shingle which will have long life and will present an attractive appearance.

Another object of the invention is to provide a shingle so designed that it may be applied to any type of roof, the same being so designed that it can be bent transversely at several places along the length thereof, thus allowing the shingles to conform with the curvature or other shape of the roof.

Another object of the invention is to provide a shingle that may be easily and economically manufactured.

I will explain the invention with reference to the accompanying drawings, which illustrate several practical embodiments thereof, to enable others familiar with the art to adopt and use the same; and will summarize in the claims the novel features of construction, and novel combinations of parts, for which protection is desired.

In said drawings:

Figure 1 is a perspective view of a portion of a roof or the like, having courses of my shingles applied thereto, in overlapping relation.

Fig. 2 is an enlarged section on the line 7P2, Fig. 1.

Fig. 3 is an enlarged section on the line 33, Fig. 2.

Fig. 4 is a top perspective view of a full-width shingle forming one embodiment of my invention.

Fig. 5 is a top perspective View of a half-width shingle used in connection with the shingle shown in Fig. 4.

Fig. 6 is .a top perspective view of a modified form of full-width shingle.

Fig. 7 is a top perspective view of a half-width shingle used in connection with the shingle shown in Fig. 6.

Fig. 8 is a bottom perspective of the lower portion of the shingle shown in Fig. 4.

Fig. 9 is a bottom perspective view of the lower end of the shingle shown in Fig. 5.

As shown in Figure 1, the shingles are adapted to be laid in horizontal courses upon the planking P of a roof supported upon beams B or the like in the usual manner.

As shown in Fig. 4, one form of shingle consists of a substantially rectangular sheet 1 of metal which is preferably made of anodized aluminum or galvanized iron. From substantially the mid-length of the shingle to the lower portion thereof the outer edge of the sheet 1 is flanged downwardly as at 1a, the flange deepening towards the lower end of the shingle, and tapering along the sides to substantially zero depth or thickness.

As shown in Fig. 8, at the center of the lower portion of flange 1a is a inturned flange 1b spaced from the body of the sheet 1 and having a V-shaped notch 10 at its center disposed on the longitudinal axis of the sheet 1, said notched flange being provided for the purpose hereinafter described. Preferably the lower corners of the shingle shown in Figs. 4 and 8 are beveled as at 1d to enhance the appearance of the shingle; however, these bevels may be omitted, if desired.

The sides of the sheet I, as shown in Fig. 4, from the ire Patet Patented July 30, 1957 ice mid-point of the length thereof to a point below the upper end of the sheet 1 are flanged upwardly as at 12, the flange being greater at the lower portion and being of substantially zero depth at the upper end of the flange 12. In the lower ends of the flanges Is is an undercut recess 1] for the purpose hereinafter described. The tapered formation of the flanges 1a and 1e permits the shingle to be readily bent transversely to conform to curvatures of the roof, the arrangement providing lines of weakness transversely of the shingle at the upper ends of the flanges 1e, and at the upper ends of the flanges 1a.

Associated with the full-width shingle shown in Fig. 4, is a half-width shingle shown in Fig. 5, which is similar in all respects to that shown in Fig. 5, the same consisting of a metallic sheet 1x having a flanged portion lax at its lower end conforming in all respects with the flange 1a of Fig. 4, except that the beveled portion 1:1 is omitted at one lower corner of the shingle. The other corner, however, contains the beveled portion ldx. The shingle shown in Fig. 5 also carries the upstanding flanges 1ex .which are similar in all respects to the flanges 1e of Fig. 4, and the flanges lex are provided with the undercut portions lfx similar to the undercut portion 1 of Fig. 4.

As shown in Fig. 9, the flange lax is provided in the unbeveled lower corner thereof with an inturned flange 1b): which is provided with a notch lcx in its adge adjacent the side flange lax, as shown in Fig. 9.

In laying the shingles, the lower course of shingles would comprise those shown in Fig. 4, all of the shingles being of the same width, and these shingles, when being laid, would initially receive nails 2 so as to secure these shingles of the course in closely adjacent parallel relation with the flanges 1e contacting and disposed parallel in the flanges 1e of the adjacent shingles at each side thereof, as shown more particularly in Figs. 1 and 3, the undercut recesses if of the flanges 1e being disposed side by side, and together forming a single slot into which the V-shaped notches 1c of the flange 1b of the overlying shingles engage, to lock the lower ends of the overlying shingles down upon the shingles directly underlying the same.

The second or next to lower course of shingles would then be laid, using as the end shingles of the said second course the shingles as shown in Figs. 5 and 9, the remaining shingles of the second course being those shown in Fig. 4. The shingles shown in Figs. 5 and 9 are used the same as those shown in Fig. 4, but the use of the shingles shown in Fig. 5 causes the second course to be staggered with respect to the shingles of the underlying course, so that the notched clips lb or lbx may register with and accurately engage the undercut recesses 1 or lfx of the upstanding flanges 1e or lex of the underlying course.

The third course of shingles would consist of a row of shingles such as shown in Fig. 4, while the next overlying course would have at each end thereof the half shingles shown in Fig. 5. Thus each alternate row of shingles would have the shingle type shown in Fig. 5 disposed at each end thereof in order to properly stagger the courses of shingles.

Instead of utilizing substantially rectangular shingles such as shown in Figs. 4 and 5, the lower portion of the shingles may be rounded, as shown in Figs. 6 and 7. In these figures the body of the shingles 1 and 1x conform in all particulars with the shingles shown in Figs. 4 and 5 except that in Fig. 6 the lower end of the shingle is rounded semi-circularly and has its periphery downturned as at laz, the same decreasing in depth from the lower end of the shingle (Fig. 6) to the portion underlying the undercut portion lfz 0f the upstanding flanges lez. The lower end of the flange laz of Fig. 6 would carry a flange 1b having a notch 1c disposed axially of the shingle in the same manner as shown in Fig. 8, the notched flange 1b being for the same purpose. Similarly, the lower end of the shingle shown in Fig. 7 has a straight side, and a rounded side forming a corner which is provided with an inturned flange lbx (Fig. 9) having a notch lcx in the manner shown in Fig. 9.

The lower ends of the shingles may be given any other desired configuration and would carry the notched flanges 1b used in the same manner as those above described in connection with the shingles shown in Figs. 4 and 5.

In applying a course of shingles above a course already laid, the nails 2 used to attach the overlying course to the roof would pass through the upper end of the underlying shingle, and thus each shingle when secured to the roof would be secured by four nails, two in the central portion thereof, and two in the upper portions thereof, the lower ends of the shingles being locked by the notched flanges lb or lbx to the underlying course of shingles. Thus, each shingle would be securely anchored to the roof. The above shingles may be readily laid without necessitating skilled labor. They will be durable and will present an attractive appearance.

Any metal or other desired material may be used for the shingles, though applicant prefers 'to use anodized aluminum or galvanized iron. The lower flanges 1a 1ax1az give strength to the lower portion of the shingle while the upstanding flanges 1e1ex-1ez having the notches 1f1fx-1fz at the lower ends thereof provide hooks for engaging the recessed flanges 1b-1bx which are formed integrally with the lower ends of the shingles, which notched flanges lock securely in the undercut portions 1f1fx of the flanges 1e1ex1ez by means of the V-cut shown in Figs. 1 and 3.

The upstanding flanges 1e-1ex-1ez, moreover, serve to support any weight that is applied to the lower end of the overlying shingle.

My shingles may be applied to any type of roof since they can be bent transversely at the upper ends of the flanges 1a1ax1az and the upper ends of the flanges 1e1ex1ez, thus allowing the shingles to conform with the curvature, concave or convex, of the roof..

Each shingle is initially nailed twice to the roof while the course is being laid, and each shingle also receives two additional nails when the next higher course is nailed to the roof. To further insure a proper seal between the courses of shingles, each shingle has an overlap at its upper end fitting well under and above the lower end of the next overlying course of shingles.

I do not limit my invention to the exact forms shown in the drawings, for obviously changes may be made therein within the scope of the claims.
